> In a world where data and AI are reshaping society, people currently have no tangible way to put their data to work for the causes they believe in. To address this, we built the Rally platform, a first-of-its-kind tool that enables you to contribute your data to specific studies and exercise consent at a granular level. Mozilla Rally puts you in control of your data while building a better Internet and a better society.

I've read all the text on this page and still have no idea what "Rally" actually is...

I guess the video may elaborate but my interest was already lost, sadly.
